Description
Technical field
The utility model is related to a kind of slope protection structure, and in particular to a kind of presplit blasting slope protection structure.
Background technology
At present, presplit blasting is widely used in the engineering such as slope excavating and tunnel piercing, but in traditional presplitting
In explosion, consolidation process is not done between pre- ceasma and side slope, to yet suffer from greatly safety hidden for some high abrupt slopes
Suffer from；When the reserved packway of side slope, the control requirement to presplit blasting will be stricter.
Utility model content
The utility model provides a kind of presplit blasting slope protection structure that can reduce explosion side slope vibration effect.
The technical solution used in the present invention is：A kind of presplit blasting slope protection structure, including being arranged on pre- ceasma and side
The multiple reinforced columns on packway are inserted between slope；Also include be arranged at side slope toe rock mass obliquely with reinforced concrete
The one-to-one anchor pole of earth pillar；Between anchor pole and corresponding reinforced column, by connecting between reinforced column
Connect reinforcing bar.
Further, the slotting ground anchor pole being additionally provided with insertion packway, and it is connected to anchor pole and corresponding reinforcing bar
On connection reinforcing bar between concrete column.
Further, the depth in the reinforced column insertion packway is identical with presplitting hole depth, and inserts horse
The gradient in road is also identical with pre- ceasma.
Further, the anchor pole is arranged on side slope toe rock mass except 45 ° obliquely.
Further, the distance between the reinforced column and pre- ceasma are 0.5m.
Further, the reinforced column number is 5 multiple, in a row per 5 reinforced column connections.
Further, the slotting ground anchor pole inserts slotting ground depth of the ground depth less than reinforced column.
Further, the angle of inclination of the slotting ground anchor pole is identical with side slope inclination angle.
The beneficial effects of the utility model are：
（1）The utility model can reduce the impact of explosion side slope vibration, can improve rushing for side slope opposing presplit blasting
Hit ability；
（2）The utility model can improve the security reliability of packway, reduce the degree of risk of engineering, improve economic effect
Benefit；
（3）It is the utility model simple structure, easy to use, it is practical.
Description of the drawings
Fig. 1 is side view of the present invention.
Fig. 2 is top view of the present invention.
In figure：1- reinforced columns, 2- anchor poles, 3- inserts ground anchor pole, and 4- connection reinforcing bars, 5- side slopes, the pre- ceasmas of 6-, 7- delays
Punching, the main blast holes of 8-, 9- packways.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described further with specific embodiment.
As shown in Figure 1-2, a kind of presplit blasting slope protection structure, inserts including being arranged between pre- ceasma 6 and side slope 5
Multiple reinforced columns 1 on packway 9；Also include be arranged at the toe rock mass of side slope 5 obliquely with reinforced column 1 one
One corresponding anchor pole 2；Between anchor pole 2 and corresponding reinforced column 1, by connection between reinforced column 1
Reinforcing bar 4.
Further, the slotting ground anchor pole 3 being additionally provided with insertion packway 9, and it is connected to anchor pole 2 and corresponding steel
On connection reinforcing bar 4 between reinforced concrete post 1；Arranging slotting ground anchor pole 3 can cause total more to consolidate.
Further, the depth in the insertion of the reinforced column 1 packway 9 is identical with the depth of pre- ceasma 6, and inserts
The gradient of packway 9 is also identical with pre- ceasma 6.
Further, the anchor pole 2 is arranged on the toe rock mass of side slope 5 except 45 ° obliquely.
Further, the distance between the reinforced column 1 and pre- ceasma 6 are 0.5m.
Further, the number of the reinforced column 1 is 5 multiple, is connected in a row per 5 reinforced columns 1.
Further, the slotting ground anchor pole 3 inserts slotting ground depth of the ground depth less than reinforced column 1.
Further, the angle of inclination of the slotting ground anchor pole 3 is identical with side slope inclination angle.
When using, first with the drilling equipment of blast hole, 0.5m or so places bore one with the depth of pre- ceasma 6 after pre- ceasma 6
Identical hole, aperture is identical with blasthole aperture, is 90mm；Spiral is inserted into, then casting concrete fixes reinforcing bar,
Form reinforced column 1；The number of reinforced column 1 is selected according to actual conditions, is connected into connection reinforcing bar 4
Row, typically connects 5-10 roots reinforced column 1 in a row；At the rock mass of the corresponding toe of side slope 5 of reinforced column 1
Squeeze into anchor pole 2 for 45 ° obliquely, then anchor pole 2 is integrally formed into structure with reinforced column 1 by being connected bar connecting；According to
Need to be arranged between reinforced column 1 and side slope and insert ground anchor pole 3, the angle of inclination for inserting ground anchor pole is identical with the inclination angle of side slope 5,
It is connected with the connection reinforcing bar 4 for being connected reinforced column 1 and anchor pole 2, strengthens integrally-built intensity；Wherein insert ground anchor pole
3 depth is smaller than the depth of reinforced column 1；So as to reduce explosion pair by changing the propagation medium of attenuation of seismic waves
The impact of side slope 5, reaches the effect of protection side slope.
The utility model can effectively reduce the vibration effect of explosion side slope, can effectively improve side slope opposing presplitting quick-fried
Broken percussion, so as to improve the safety reliability of packway, reduces the degree of risk of engineering, increases economic efficiency.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
